11 Supported Versions 1.4 Supported Versions The IBM DB2 Database plug-in supports the following versions of products: Enterprise Manager Cloud Control 13c: The plug-in is certified for the latest release of Oracle Enterprise Manager Cloud Control 13c Release 5 ( ) and higher (Oracle Management Server (OMS) and Oracle Management Agent). Version 9.1, 9.5, 9.7, 10.1, and 10.5 of single-partition IBM DB2 Universal Database (UDB) for Linux, UNIX, and Windows (LUW). IBM DB2 configured for High Availability and Disaster Recovery (HADR). 1.5 IBM DB2 Database Plug-in Prerequisites The following prerequisites must be met before you can use the plug-in: 1. Install the following: Enterprise Manager Cloud Control 13c ( ) or higher (Oracle Management Service and Oracle Management Agent). Install the Inventory and Usage Patch ( ), available from My Oracle Support ( IBM DB2 Universal JDBC Type 4 driver for IBM DB2 Database (see Setting Up the JDBC Driver) IBM DB2 Universal Database 2. Create a suitable operating system user to access the table functions used in IBM DB2. For information about creating a user, see Using a Suitable Operating System User and Assigning Authorities and Privileges. 3. To avoid metric collection errors for Database Monitoring metrics, create the table STMG_DBSIZE_INFO. For more information, see Configurations Required for Avoiding Metric Collection Errors for Database Monitoring Metrics. 4. To configure your Management Agent to generate alerts using the IBM DB2 Diagnostic Log file (db2diag.log), then do the following: Define your match patterns in the Diag_log_file_match_pattern_file.txt file that is present in $ORACLE_HOME/plugins/oracle.em.sidb/scripts/emx/ ibm_db2_database/. Define your ignore patterns in the Diag_log_file_no_match_pattern_file.txt file that is present in $ORACLE_HOME/plugins/oracle.em.sidb/scripts/emx/ ibm_db2_database/. Set the DIAG_PATH configuration parameter of the database manager (instance) to correspond to the monitored IBM DB2 database. IBM DB2 Database Plug-in Overview and Prerequisites 1-5

12 Setting Up the JDBC Driver For performance reasons, you should set a maximum diagnostic log file size of 100 MB when this metric is enabled. You can set the maximum file size using the command: db2 update dbm cfg using diagsize 100 Based on the patterns defined in the two files, the System Monitoring Plug-in for IBM DB2 parses the Diagnostic Log file and generates alerts for the satisfied conditions. First, the plug-in validates the two files to see if any patterns are defined. If no patterns are defined, then the plug-in does not parse the Diagnostic Log file. If matching patterns are not defined, but ignore patterns are defined, then the plug-in parses every entry in the Diagnostic Log file and checks if ignore patterns are satisfied. If matching patterns are also defined, then the plug-in first parses only those entries that satisfy the matching patterns, and then for those satisfied entries, the plug-in checks if ignore patterns are satisfied. Also, if multiple log entries having the same function name are encountered in a collection, then only one alert is generated to represent the function name. This alert is based on the last log entry with a common function name, present in the Diagnostic Log file. Note: This feature is supported only for local monitoring, that is, when the IBM DB2 database on a host is monitored by an Oracle Management Agent that is running on the same host. 5. In the IBM DB2 Database SQL Statement Performance and IBM DB2 Database Applications Lock Performance reports and the Agent Monitoring metric, in order to see the SQL statement text along with the application name, enable the instance configuration parameter DFT_MON_STMT. Otherwise, you may not see any data in the column. 6. As part of JDBC URL, either IP Address or host name can be provided. Ensure that the host name can be resolved consistently on the network. Standard TCP tools such as "nslookup" and "traceroute" can be used to verify the host name. Validate using the following commands on Management Agent where plug-in is deployed: nslookup <host name> This returns the IP address and fully qualified host name. nslookup <IP> 1.6 Setting Up the JDBC Driver This returns the IP address and fully qualified host name. The JDBC driver is available from IBM, and consists of the following files that the Agent must be able to access: db2jcc.jar db2jcc_license_cu.jar To set up the AGENT_BASE_DIR directory for the IBM DB2 Universal Type 4 JDBC driver: 1-6 IBM DB2 Database Plug-in User's Guide

13 Deploying the Plug-in 1. If it does not already exist, create the directory $AGENT_BASE_DIR/plugins/ dependencies/oracle.em.sidb/jdbcdriver/. 2. Copy the three JDBC driver files into the directory $AGENT_BASE_DIR/plugins/ dependencies/oracle.em.sidb/jdbcdriver/. Note: If you do not have access to or cannot find your db2jcc.jar driver, you can download a copy of it from IBM's support site: Deploying the Plug-in You can deploy the plug-in to an Oracle Management Service instance using the Enterprise Manager Cloud Control console, or using the Enterprise Manager Command-Line Interface (EMCLI). While the console enables you to deploy one plugin at a time, the command line interface mode enables you to deploy multiple plug-ins at a time, thus saving plug-in deployment time and downtime, if applicable. See the Managing Plug-ins chapter in the Oracle Enterprise Manager Cloud Control Administrator's Guide for instructions on deploying the plug-in. 1.8 Upgrading the Plug-in The Self Update feature allows you to expand Enterprise Manager's capabilities by updating Enterprise Manager components whenever new or updated features become available. Updated plug-ins are made available via the Enterprise Manager Store, an external site that is periodically checked by Enterprise Manager Cloud Control to obtain information about updates ready for download. See the Updating Cloud Control chapter in the Oracle Enterprise Manager Cloud Control Administrator's Guide for steps to update the plug-in: Undeploying the Plug-in See the Managing Plug-ins chapter in the Oracle Enterprise Manager Cloud Control Administrator's Guide for steps to undeploy the plug-in.

15 2 Configuring the IBM DB2 Database Plug-in This chapter provides the instructions for the configuration tasks you must complete before adding an IBM DB2 Database target to Enterprise Manager Cloud Control. The following configuration tasks are provided: Configure the Management Agent to Deploy the Plug-In Using a Suitable Operating System User and Assigning Authorities and Privileges Configuring IBM DB2 for Health Indicator Metrics and Database Monitoring Metrics 2.1 Configure the Management Agent to Deploy the Plug-In To configure the Agent, you must first ensure that the user starting the Agent service belongs to the Local Administrators Group. Also, you must set the preferred credentials on all Agents where you want to deploy the plug-in. To do so, follow the instructions given in the following sections: Assigning Advanced Privileges to User Setting and Validating Preferred Credentials Assigning Advanced Privileges to User To assign advanced privileges, do the following: 1. Locally on the Microsoft Windows node hosting the Agent, check that the user starting the Agent service belongs to the Local Administrators Group. If not, add it. 2. Open the Local Security Settings Windows Tool and give the following Advanced Privileges to the user starting the Agent service: Act as part of the operating system Adjust memory quotas for a process Logon as batch job Replace a process level token 3. Restart the Agent service if it is running. 4. Set the Preferred Credentials for the Host and the Agent in Cloud Control. For more information, see Setting and Validating Preferred Credentials. The OS user set in the Preferred Credentials must belong to the Local Administrators Group. Configuring the IBM DB2 Database Plug-in 2-1

16 Using a Suitable Operating System User and Assigning Authorities and Privileges This OS user must have the following Advanced Privileges: Act as part of the operating system Adjust memory quotas for a process Log on as batch job Replace a process level token Setting and Validating Preferred Credentials To set the preferred credentials on all Agents where you want to deploy the plug-in, do the following: 1. In Enterprise Manager Cloud Control, from the Setup menu, select Security, then Preferred Credentials. The Preferred Credentials page appears, showing a table of targets. 2. Select Host target type from the table and then click Managed Preferred Credentials. The Host Preferred Credentials page appears. 3. In the Host Preferred Credentials page, in the Target Credentials section, select the host that is running the Management Agent where the plug-in has to be deployed, and click Set. 4. In the Select Named Credential dialog box, Select Credential as New and specify the user name and password and click Test and Save. If your test runs successfully, your credentials are set correctly. 5. Run the OS Command job for the Management Agent where the plug-in has to be deployed. Log in to Enterprise Manager Cloud Control. From the Enterprise menu, select Job and then Activity. In the Job Activity page, from the Create Job list, select OS Command, and click Go. Fill up the details required in the following pages, and click Submit to run the job. If the job runs successfully, your credentials are set correctly. Note: In order to run jobs from the UI, the target's Agent Host Preferred Credentials must be for a user that can run the db2 command-line utility and has permissions to start, stop, quiesce, and unquiesce the IBM DB2 database. 2.2 Using a Suitable Operating System User and Assigning Authorities and Privileges The IBM DB2 Database plug-in accesses the table functions used in IBM DB2. For the plug-in to have access to the table functions, you have to use a suitable operating 2-2 IBM DB2 Database Plug-in User's Guide

17 Using a Suitable Operating System User and Assigning Authorities and Privileges system user and assign this new user to a user group. The operating system user must have at least the minimum privileges. In addition, you have to assign the correct authority levels to this user. Note: IBM DB2 users must be operating system users. IBM DB2 cannot have its own database users because it relies on the host operating system for security. If you do not have an operating system user already created, first, create one on the host where IBM DB2 is running. Then, follow these steps to assign this user to a new or existing UserGroup: 1. Open the IBM Data Studio. 2. From the tree view, select the database that you wish to modify, and connect using an admin account as shown in Figure 2-1: Figure 2-1 Connect to IBM Data Studio 3. From the tree view, expand Users and Groups and select Users. 4. From the right pane, select Create a New Object. 5. In the General tab of the Properties window for the New User, enter the operating system user name. 6. From the Privileges tab, verify that the account is granted CONNECT. 7. To verify the applied changes, try connecting to the database with the newly created user as shown in Figure 2-2: Configuring the IBM DB2 Database Plug-in 2-3

18 Using a Suitable Operating System User and Assigning Authorities and Privileges Figure 2-2 Connect to Database Note: These steps can also be performed from the command line using IBM DB2 SQL. Also, assign authorities and privileges for the operating system UserGroup. The authorities supported with IBM DB2 are SYSADM, SYSCTRL, SYSMAINT, DBADM, and LOAD. The SYSADM, SYSCTRL, and SYSMAINT authorities cannot be granted using the GRANT SQL statement. These special authorities can only be set from the database manager configuration file. DBADM privilege can only be granted by user at SYSADM authorization level. SYSMON authority level is required to monitor IBM DB2. This level is required to access the table functions, such as SYSPROC.SNAPSHOT_DATABASE, which are used in IBM DB2. Follow these steps to set SYSMON authority level to your UserGroup: 1. At the db2=> prompt, run the following commands: db2 => update dbm cfg using sysmon_group USERGROUP db2 => db2stop db2 => db2start 2. To check whether the changes are effective, run the following command: db2 => get dbm cfg The following will be the output of the previous command: Database Manager Configuration Node type = Enterprise Server Edition with local and remote clients... SYSADM group name (SYSADM_GROUP) = SYSCTRL group name (SYSCTRL_GROUP) = SYSMAINT group name (SYSMAINT_GROUP) = 2-4 IBM DB2 Database Plug-in User's Guide

19 Configuring IBM DB2 for Health Indicator Metrics and Database Monitoring Metrics SYSMON group name (SYSMON_GROUP) = USERGROUP... Note: To understand how authorities and privileges are implemented in IBM DB2, access the IBM website. 2.3 Configuring IBM DB2 for Health Indicator Metrics and Database Monitoring Metrics The following sections explain the post-installation configuration steps you need to perform on IBM DB2: Configurations Required for Health Indicator Metrics Configurations Required for Avoiding Metric Collection Errors for Database Monitoring Metrics Configurations Required for Statement Monitoring Configurations Required for Lock and Lock Waits Monitoring Configurations Required for Database Collection Health Indicator Metric Configurations Required for Health Indicator Metrics The health indicators for instance and database objects are enabled and disabled using the database manager configuration parameter HEALTH_MON. Then, the table functions HEALTH_TBS_HI, HEALTH_DB_HI, and HEALTH_DBM_HI get populated. These functions are used by the plug-in to show the alerts triggered based on the thresholds of health indicators. Note: Enabling these settings may result in some overheads, such as CPU and memory. Therefore, follow these steps only if you want to view the Health Indicator metrics. To enable or disable HEALTH_MON by CLP (Command Line Processor), run the following command: db2==> update dbm cfg using HEALTH_MON [on;off] To check if your changes are effective, run the following command: db2==> get dbm cfg The following is the output: Monitor health of instance and databases (HEALTH_MON) = ON Configuring the IBM DB2 Database Plug-in 2-5

20 Configuring IBM DB2 for Health Indicator Metrics and Database Monitoring Metrics For more information, access the IBM website Configurations Required for Avoiding Metric Collection Errors for Database Monitoring Metrics To avoid metric collection errors for the "Database Monitoring" metrics, make a call to the GET_DBSIZE_INFO package so that the STMG_DBSIZE_INFO table gets created and populated with the required data. The GET_DBSIZE_INFO procedure calculates the database size and maximum capacity. The calculated values are returned as procedure output parameters and cached in the SYSTOOLS.STMG_DBSIZE_INFO table. The procedure caches these values because the calculations are costly. The SYSTOOLS.STMG_DBSIZE_INFO table is created automatically the first time the procedure runs. If there are values cached in the SYSTOOLS.STMG_DBSIZE_INFO table and they are current enough, as determined by the snapshot-timestamp and refresh-window values, then these cached values are returned. If the cached values are not current enough, new cached values are calculated, inserted into the SYSTOOLS.STMG_DBSIZE_INFO table and returned, and the snapshottimestamp value is updated. The last parameter in the GET_DBSIZE_INFO call is refresh window. Default value refresh window (time difference between successive calls) is 30 minutes. If your database is growing at a faster rate, then you can set a lower value. To make a call to GET_DBSIZE_INFO by CLP, run the following command: db2==>call GET_DBSIZE_INFO(?,?,?, -1) In this case, the refresh window is 30 minutes. For more information, access the following page on the IBM website: topic=/com.ibm.db2.luw.sql.rtn.doc/doc/r html Configurations Required for Statement Monitoring To avoid metric collection errors for the statement monitoring metrics, run the following command at the DB2 prompt to update the database manager configuration so the switch for monitoring statements is on: db2 => update dbm cfg using DFT_MON_STMT on Configurations Required for Lock and Lock Waits Monitoring To avoid metric collection errors for the lock and lock waits information in the analysis page, run the following command at the DB2 prompt to set up permissions so the monitoring plug-in user can query the lock waits administrative view in DB2. For IBM DB2 Versions 9.1 and 9.5, update the database manager configuration so the switch for locks and lock waits is on: db2 => update dvm cfg using DFT_MON_LOCK on For IBM DB2 Versions 9.7 and above, ensure that the DB2 user has select permission on MON_LOCKWAITS administrative view, and has DATAACCESS authority. Run the following commands where '[username]' is the monitoring user name used when configuring the target: 2-6 IBM DB2 Database Plug-in User's Guide
